Step 1

Preheat the oven to 220ºC (200ºC fan oven) mark Sift the flour into a bowl, add a pinch of salt and mix. Add the butter, cut into small cubes, then lightly rub in with fingertips until mixture looks like breadcrumbs. Add sugar and stir in.

Step 2

Put the egg into a jug, add 2tbsp of the buttermilk or milk and beat together. Make a well in the centre of the crumble and add the egg mixture. Using a round-bladed knife, mix the egg gradually into the crumble. As the dough forms, bring it together with your hands; it should be soft but not sticky. If it feels dry, add extra buttermilk or milk, 1tsp at a time. Shape the dough into a rough ball, then pat into a round.

Step 3

Lightly flour a clean worksurface and a rolling pin. Gently roll out the dough to at least 2.5cm thick. Dip a 5cm cutter in flour. Cut out each scone by placing the cutter on the dough and giving it a quick push down-wards. Don't twist the cutter; just lift it and ease the dough out. You'll get five or six scones out of the round. Gather the trimmings, re-roll to the same thickness and cut more, repeating until you have a total of eight.

Step 4

Dust a large baking tray with flour and arrange the scones on it. Lightly brush each one with buttermilk or milk, then dust with a little more flour. Bake on the top shelf of the oven for 10-12min, or until well risen and golden. Transfer scones to a wire rack to cool for 5min or until just warm. Slice them in half and serve with unsalted butter or with clotted cream and strawberry jam.
